I have seen this on a couple bikes. What is it's purpose?
There is one in the first picture on this page: http://www.sheldonbrown.com/frame-spacing.html

it's to hang your chain on when the wheel is removed.
Thanks. That makes sense. I think I'll leave it on. I'm converting a bike to single speed, and am cutting off the derailure hanger and cable guides.
Might as well cut that off for the single-speed too. It needs the RD's spring-tension to hold it taut on that little post.
Wouldn't it just sort of dangle there if you don't move the bike too much? Might be a useful third hand for flip-flopping the wheel.

Keep it. I have a fixed gear conversion that has a chain hanger and it's pretty useful when changing wheels, fixing flats, whatever.
I never used mine for the last 11-12 years... on my Old Trek MTB.
For the last couple months, I wondered WHY! LMAO
